Weather in December
Temperature
The onset of December brings with it an average high-temperature of a still moderately hot 27°C (80.6°F), showing a negligible variation from the month before. Guanabacoa, during the month of December, experiences an average low-temperature of 19.9°C (67.8°F).Heat index
December's heat index is evaluated at a tropical 30°C (86°F). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
